Original question:

TMAG5273: Wake-up & sleep with interrupt when a threshold is crossed seems to get stuck

TMAG5170: Does the TMAG5170 have similar W&S issues as observed in the TMAG5273?

Hi Experts,

Seeking your assistance on this query from Cx. As discussed here: 

 the TMAG5273 has an issue with the W&S functionality. We observe the same issue with this sensor.

Isaac Lara recommends the SPI variant, the TMAG5170. Since it seems to be a very similar device. Can say something about if there are possible (similar) issues with the TMAG5170 as well?

Regards,
Archie A.

    Hello Archie,

    Thanks for posting to the sensing forum! We have not encountered an issue with the TMAG5170 W&S hence it has been suggested to the customer. We believe the W&S issue on TMAG5273 occurs in some instances due to the speed of the I2C bus.

    We do not have much info on that issue since we have only been able to replicate it at slower I2C clock frequencies but not at fast ones. The TMAG5170 uses a SPI interface instead of I2C so these are completely different blocks.

    I hope this helps!

    Best,

    Isaac
